EclipseLink Core 4.0.2 · org.eclipse.persistence.queries

Modifier and Type	Interface and Description
public interface	Call Call defines the interface used primarily by EclipseLink queries and query mechanisms to perform the necessary actions (read, insert, update, delete) on the data store.
public interface	FetchGroupTracker Purpose: The fetch group tracker interface provides a set of APIs which the domain object must implement, in order to take advantage of the EclipseLink fetch group performance enhancement feature.
public interface	JPAQueryBuilder This interface defines the entry point for implementing a JPQL query parsing system in EclipseLink.
public interface	QueryRedirector Purpose: Query redirection allows for a named or parameterized query (or finder) to dynamically determine how the query is to be executed based on the arguments.

Class Summary

Modifier and Type	Class and Description
public class	AttributeGroup Purpose: An AttributeGroup represents a set of mappings and nested AttributeGroups for relationship mappings for an entity type.
public class	BatchFetchPolicy BatchFetchPolicy defines batch reading configuration.
public class	ColumnResult Purpose: Concrete class to represent the ColumnResult structure as defined by the EJB 3.0 Persistence specification.
public class	ComplexQueryResult Purpose: Used to return multiple sets of information from a query.
public class	ConstructorReportItem Purpose: An item specifying a class constructor method to be used in a ReportQuery's returned results.
public class	ConstructorResult Purpose: Concrete class to represent the ConstructorResult structure as defined by the JPA 2.1 Persistence specification.
public abstract class	Cursor Purpose: Abstract class for CursoredStream and ScrolableCursor
public class	CursoredStream Purpose: Stream class which is used to deal with large collections returned from TOPLink queries more efficiently.
public class	CursoredStreamPolicy Purpose: Used to support cursored streams in a read query.
public abstract class	CursorPolicy Purpose: Abstract class for all Cursor-related policy objects
public abstract class	DatabaseQuery Purpose: Abstract class for all database query objects.
public class	DataModifyQuery Purpose: Concrete class used for executing non selecting SQL strings.
public class	DataReadQuery Purpose: Concrete class to perform read using raw SQL.
public class	DeleteAllQuery Purpose: Query used to delete a collection of objects.
public class	DeleteObjectQuery Purpose: Used for deleting objects.
public class	DirectReadQuery Purpose: Concrete class to perform a direct read.
public class	DoesExistQuery Purpose: This should only be used by the descriptor, this should not be executed directly.
public class	EntityResult Purpose: Concrete class to represent the EntityResult structure as defined by the EJB 3.0 Persistence specification.
public class	FetchGroup A FetchGroup is a performance enhancement that allows a group of attributes of an object to be loaded on demand, which means that the data for an attribute might not loaded from the underlying data source until an explicit access call for the attribute first occurs.
public class	FieldResult Purpose: Concrete class to represent the FieldResult structure as defined by the EJB 3.0 Persistence specification.
public class	InMemoryQueryIndirectionPolicy Purpose: Provide a means of controlling the behavior of in-memory and conforming queries that access un-instantiated indirection objects in processing the query against cached objects.
public class	InsertObjectQuery Purpose: Used for inserting new objects into the database.
public class	JPQLCall Purpose: Used as an abstraction of a database invocation.
public class	LoadGroup Purpose: Used to load specified relationship attributes and nested relationship attributes.
public class	MethodBaseQueryRedirector Purpose: Allows a class to be a `QueryRedirector` without implementing `QueryRedirector`.
public abstract class	ModifyAllQuery PUBLIC: Query used to perform a bulk delete using the expression framework.
public abstract class	ModifyQuery Purpose: Abstract class for all modify queries.
public abstract class	ObjectBuildingQuery Purpose: Abstract class for all read queries that build objects and potentially manipulate the TopLink cache.
public abstract class	ObjectLevelModifyQuery Purpose: Abstract class for all object modify queries.
public abstract class	ObjectLevelReadQuery Purpose: Abstract class for all read queries using objects.
public class	QueryByExamplePolicy Purpose: This policy defines the configuration options for a Query By Example query.
public class	QueryRedirectorHelper Purpose: The purpose of this class is to provide the query redirector with some helper methods for general EclipseLink operations (such as checking a query against the cache) which may not occur because the query is being redirected.
public class	QueryResultsCachePolicy PUBLIC: A QueryResultsCache policy dictates how a query's results will be cached.
public class	ReadAllQuery Purpose: Concrete class for all read queries involving a collection of objects.
public class	ReadObjectQuery Purpose: Concrete class for all read queries involving a single object.
public abstract class	ReadQuery Purpose: Abstract class for all read queries.
public class	ReportQuery Purpose: Query for information about a set of objects instead of the objects themselves.
public class	ReportQueryResult Purpose: A single row (type) result for a ReportQuery Description: Represents a single row of attribute values (converted using mapping) for a ReportQuery.
public class	ResultSetMappingQuery Purpose: Concrete class to perform read using raw SQL and the SQLResultSetMapping.
public class	ScrollableCursor
public class	ScrollableCursorPolicy PUBLIC: ScrollableCursorPolicy allows for additional options to be specified for ReadAllQuery or DataReadQuery.
public class	SQLCall Purpose: Used as an abstraction of an SQL call.
public abstract class	SQLResult Purpose: An abstract superclass that represents the commonalities between the main result types of the SQLResultSetMapping
public class	SQLResultSetMapping Purpose: Concrete class to represent the SQLResultSetMapping structure as defined by the EJB 3.0 Persistence specification.
public class	StoredFunctionCall Purpose: Used to define a platform independent function call.
public class	StoredProcedureCall Purpose: Used to define a platform independent procedure call.
public class	UpdateAllQuery PUBLIC: A Query Class used to perform a bulk update using TopLink's expression framework.
public class	UpdateObjectQuery Purpose: Used for updating existing objects into the database.
public class	ValueReadQuery Purpose: Concrete class to perform a read of a single data value.
public class	WriteObjectQuery Purpose: Used for inserting or updating objects WriteObjectQuery determines whether to perform a insert or an update on the database.
